ALLOY.

- SPECIFICATION forming part of Letters Patent No. 655,392, dated August'7, 1900.

Application filed March 13, 1900.

To all whom it may concern:

Be it known that we, GUILLIAM H. OLAMER and JOSEPH G. HENDRIoKsoN,citizens of the United States, residing at the city of Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented acertain new and useful Alloy, of which the following is a specification.

The object of the present invention is to provide for the convenientaddition of tin,

lead, and nickel to copper or copper compositions, so as to makeso-called composition castings. It may be remarked that the addition ofnickel to such castings brings about a homogeneous distribution of leadand also prevents segregation. Lead is valuable in these castings,because it makes them solid and easily workable.

An alloy embodying the invention consists of lead, tin, and nickel insubstantially the following proportions: lead,fortyfive tin, fortyfive,and nickel, ten, and it is used by melting it along with copper orcopper-bearing material in the proportion of, for example, one part ofalloy to ten parts of copper, more or less. An alloy embodying thepresent invention Serial No. 8,493. (No specimens.)

may be made as follows: Nickel is added to tin. However, the nickel isreadily soluble in melted tin, so that the amount which may be addeddepends only on temperature and time given for the solution. Thetemperature required is only a red heat and is far below themelting-point of nickel. After the tin has absorbed the requisite amountof nickel the lead is added to form the finished product. It is thencast in suitable molds in bars of convenient size.

Having thus described the nature and objects of our invention, what weclaim as new, and desire to secure by Letters Patent, is-

A composition for admixture to copper castings which consists of analloy of lead, tin and nickel, substantially as described.

In testimony whereof we have hereunto signed our names in the presenceof two witnesses.

G. H. CLAMER. J. G. HENDRIOKSON.
